Virgin America flights from $49

Update: United Airlines is also having a fare sale when you book before Feb. 6 and travel by April 20. Sale fares are for Tuesday, Wednesday and Saturday flights.

Just got word of a massive flight sale on Virgin America for flights from L.A., San Diego and Las Vegas. Flights are $49-$119 each way through April 1. Book by Feb. 8, though the best flights will go sooner than that.
